The side wall and roof plate of the comprehensive pipe gallery are waterproof and anti-corrosion
Project Overview:
In April 2015, Haikou became one of the first 10 pilot cities of underground comprehensive pipe corridors in China.According to the Special Plan of Haikou Underground Comprehensive Pipeline Corridor, a 222.1 km underground comprehensive pipe corridor will be built in Haikou by 2030.Up to now, the Changbin Road project has entered the trial operation stage.The underground comprehensive pipe gallery integrates electric power, communication, gas, heating, water supply and other engineering pipelines, which is an important infrastructure and "lifeline" to ensure urban operation.
In order to ensure the internal operation environment of the pipe gallery, prevent the leakage of water and isolate the erosion of external adverse factors, the traditional waterproof materials, such as waterproof roll and quick condensing rubber waterproof coating, are chosen to build a waterproof layer beyond the efficient and long-term performance of the pipe gallery.
construction procedure:
First time sprinkling wetting base surface first time (150ml / m2) second time sprinkling second time (100ml / m2) third time sprinkling wet maintenance for 3 days
Effect evaluation:
The penetration depth of Jiagushi material is 30~50mm, which will not be damaged by sharp objects, effectively protect the steel bar, significantly improve the strength and seepage resistance grade of the concrete, and prevent water seepage.Waterproof layer is continuous, no connection, fine cracks can automatically heal.
